• Introduction:

  We aim to identify factors associated with surgical refusal and non-surgical candidacy in clinical stage I kidney masses and to evaluate their impact on overall survival (OS).

  Materials and methods:

  We conducted a retrospective cohort study using the National Cancer Database of patients with clinical stage I kidney cancer between 2004 and 2017. Logistic regression was used to determine baseline sociodemographic-, clinical-, and treatment facility-related factors associated with surgical refusal and non-surgical candidacy. Patients were 1.1 propensity score-matched and Cox regression analysis evaluated the impact of surgical refusal and non-surgical candidacy on OS.

  Results:

  Compared to those who underwent surgery, those who refused surgery and those who were non-surgical candidates were more likely to be older, female, non-Hispanic (NH) Black, uninsured, have multiple comorbidities, and traveled a shorter distance to care. Similarly, compared to non-surgical candidates, those who refused surgery were more likely to be younger and have a tumor size ≥ 4.0 cm. Those who refused surgery had significantly lower median survival time and worse OS than those who underwent surgery (HR: 3.18, 95% CI: 2.85, 3.54). Non-surgical candidates had significantly lower median survival time and lower OS than those who had surgery (HR: 4.16, 95% CI: 3.84, 4.51).

  Conclusion:

  Various socioeconomic, demographic, and clinical factors are associated with patients refusing to undergo surgery, which in turn leads to lower overall survival rates in stage I kidney cancer patients. Recognizing these factors will enable healthcare professionals to address and potentially alleviate these issues, ultimately ensuring that patients receive the most appropriate care.
